To all ic-horn, it may comm: 1

Be it known thatI, Hnnnr wlismvnii,

a citizen of the United States, and a residentiofDanville, the countyof Vermilion and State of Illinois,.have invented certain new and useful Improvements in Heating Stoves, of which the following is a specification. I

. My inventionrelates to heating stoves, and it consists in the combinations, constructions and arrangements herein described andclaimed."

An object of my invention to provide: a heating stove of simple constructionwhich is provided with means for c'onducting air to'ithe Icombustion chamber to mingle with the-combustible gases therein, whereby such gases are consumed within the stove and a great. economy; thus. effected in that prac tically all the combustibleelements in a fuel charge are utilized in the generation of heatr 'v v A further object of my invention isjto provide in a stove of the character described, a novel means for causing the induction of cold air from the upper end of thestove to the firebox and for deflecting the ascending heated current" radially, thereby occasioning the radiation of a maximum amount of the heat generated in the stove.

Other objects and advantages will be apparent from the following description and the novel features of the invention will be particularly outlined in y the appended claims.

My invention is illustrated in the accompanying drawing, forming a part of this application, in which: I

Fig. 1 is a view, mainly sectional, and partly in side elevation, of a stove embodymg the invention,

Fig. 2 is a section along the line 22 of Fi 1, and

1g. 3 1s a section along the line 33 of has an upper end 5 provided with an open ing 6 adjacent to one edge thereof, to which a smoke pipe or flue 7 is joined.

The upper end 5 is provided also with a central opening into which fits the upper endof frustoeconical member 8.". The flat -b ter has a length substantially the same as that'of the body or drum 1 and is provided with an integral outwardly extending anf nular flange '9. at its lower end, which flange is of suflicient size diametrically to closely interfit the body or druml, whereby a subu stantially airtight joint isprovided between the flange and the inner ordruml,v

Thefrusto-conical member 8 is provi ded wall ,of the bodywith an upper end 10 having a plurality of,

openings 11 formed therein and a rotary register valve12 having-a plurality of openmgs 13. therethrough .is mounted upon the endlO. :lhe number and arrangement of openings18 are respectively the. same as thenumberjand arrangement of the open ings lland' each of the openingsldhasthe same areaas each of the openings 11,:where the registerevalve .12 may be rotated as desired ,to vary the, volume ofQair permitted I to enter the frust o-coni cal memberB at the upper end thereof. i

A plurality of spaced openings 14 are formed through the flange 9. The fire pot 2 has an inclined inlet 15 located below the plane of the flange-9 and normally closed at its outer end by 'a hingedly attached fuel door 16 which is imperforate and'is normally maintained in closed position, as

illustrated, by the influence of gravity. A

grate 17 is positioned within the fire pot 2 at the lower end thereof. I

From the foregoing description of the various parts of the device, the operation.

thereof may be readily understood. A

quantity of fuel to, beburntis fed througlh the inlet 15 and rests upon the grate.

door or damper 18 in the ash pit 3 is opened and the fuel resting upon the grate 1s ignited. After a short interval, the door or damper 18 is closed and remains closed I thereafter. The register valve 12 is turned to admit a desired volume of cold air at the upper end of the frusto-conical member 8.- The cold air will pass downward within the frusto-conical member 8, as indicated by the arrowsin Fig. 1, and upon entering'the fire pot 2 will mingle; with the gases therein, which gases may be practically completely consumed when mixed with the admitted air.. Ordinarily, such gases pass, directly to the upper part of the'body or drum and thence through the flue 7 without: being consumed, thereby causing'a considerab-lewaste.

The heated. currents, comprising the products of combustion, are deflected outwardly by the admitted currents of colder air and by the flange 9. Such heated currents pass through the openings 14 and then pass upward close to the inner wall of the body or drum 1, thereby insuring the radiation of practically all the heat generated. I have found in practice that the best results are obtained when the respective openings 11, 13, and 9 are formed in such manner that the aggregate area of each set of openings is the same as that of every other set of openings and the same as the area of the ingress end of, the flue 7. However, good results may be obtained when the aggregate areas of the respective sets of openings vary from the proportion'stated. v

Obviously my invention is susceptible of embodiment in forms varying in detail from that illustrated and described in the accompanying drawing and in the foregoing'description, and I therefore consider as my own, all such modifications and adaptations of the form of the device illustrated and described which properly fall within the scope of the invention as outlined in the appended claims.

1. A stove comprising a fire pot, a substantially cylindrical stove body mounted i sa-asethereon and being provided with an upper end, saidupper end having a central opening for the admission of cold air and an outlet locatedadjacent to one edge thereof, a frusto-conical member having the smaller end thereof received within the said central opening and being provided with an end having openings therethrough, said frusto conical member having a length substantially equal to that of the stove body and being formed with an outwardly extending annular flange at its lower end closely fitting within the stove body, said flange having a plurality of spaced openings therethrough, and a valve for controlling the openings through the end of the trusto conical member.

2. In a stove, a frusto-conical deflecting member having an outwardly extending flange at its larger end and being provided with a closure at its other end, said flange having a plurality of spaced openings there through and said closure being formed with a plurality of openings therethrough, the

aggregate'area of the openings through said flange being substantially the same as the aggregate areaof the openings through said closure, and means for controlling the openings through the closure.
